Hi all I own a 94 wrx import and today when I got up it took a while to get started once it fired it took a while so I could even rev it, I'm assuming the icy morning will have something to do with it as it's fine now warm. Any ideas?


Cheers

coolant temp sensor giving up.

Another vote for temp sensor. If it tells the ECU it thinks the engine is warm then it won't enrich the mix for cold starting/running.

hi there, cheers for that,im just trying to find it now lol.

i have just noticed a vacumn pipe off that goes to the charcoal cannister could this have caused the hard starting when cold?

my 93 wrx does not cold start very well when using tesco 99 ron.
